The case for precision metals as a 21st-century strategic reserve.
GUEST ESSAY · IN PROGRESS

The case for precision metals as a 21st-century strategic reserve.

Not a commodity argument — an industrial-sovereignty argument.

EMI shielding from first principles.
GUEST ESSAY · IN PROGRESS

EMI shielding from first principles.

How magnetic permeability, electrical conductivity, and skin depth conspire to make nickel a near-ideal shielding material across RF and microwave frequencies.

Why NP1 nickel wire outperforms platinum in hydrogen electrolysers.
GUEST ESSAY · IN PROGRESS

Why NP1 nickel wire outperforms platinum in hydrogen electrolysers.

A materials trade-off that the hydrogen build-out is about to rediscover.

From –196 °C to 1,000 °C: aerospace structural integrity of ultra-pure nickel.
GUEST ESSAY

From –196 °C to 1,000 °C: aerospace structural integrity of ultra-pure nickel.

Cryogenic tankage and hot-section turbine structures impose opposite constraints. Ultra-pure nickel and its alloy family meet both — and why that matters for a regulated digital security backed by aerospace-grade feedstock.

What 99.99% purity actually means.
GUEST ESSAY

What 99.99% purity actually means.

A materials scientist’s explanation of the NP1 grade, the GOST 492 standard, and why precision nickel is priced unlike commodity nickel.

Nickel — the silent metal quietly powering the 21st-century technology boom.
GUEST ESSAY

Nickel — the silent metal quietly powering the 21st-century technology boom.

From hydrogen electrolysers to EMI shielding, aerospace alloys to compound semiconductors, ultra-pure nickel is the material layer under a generation of technologies. Why the market has not yet noticed.
